Pretty boat, but I'm biased. ;)

Wonder how many hours it has. Probably pretty nice for barefooting!

Supercharger? The boat looks very nice.

Wow...that boat is in beautiful shape. I wonder what the reserve is? I don't see any mods to the dog house....surprised that all fit under there!!!

Let us know what you get for a response on performance.

If you enlarge the pictures, it looks like hey made a smaller clam shell type box. I see about a 3 or so inch lip all the way around on the floor. Must have a slightly taller pylon too to clear it I would guess. great looking boat, the OE prop ihas a few dings on the tips. Could get better performance from the boat with a new prop. I am surprised the OE prop has enough bite at anything close to WOT.
I would do that if I could! LOL

93.5 according to the description. Crying shame to own a boat that long and only use it 93 hours.

haven't heard back yet... can't wait to find out what this thing runs! A 205 of that era that runs 50mph just might be the perfect boat.

I bet that babby blower only adds 4 to 6 mph. if hes useing normal boost pullies He should of added pitch to the prop to get the most out of it. Wish my 205 had 93 hours hell I do that in 2 years! Cant wait to see the performance post.

I had a BM babby blower on a 454 in a 25 foot Checkmate Convinsor it picked up 8 mph. only after twisting the engine to 5,200. Finally blew up after I sold it 2 years later. With the stock prop it only increased about 5 mph. hardly worth the expense. Big acceleration gains though.

I considered doing that to get more clearance when I installed the Edelbrock intake on mine (before I found the low profile flame arrestor. I don't think he would need to raise the pylon. If I recall correctly, the early 90s boats have a fair amount of clearance to begin with?

Great looking boat. I'm always a little surprised to see how well some people baby their boat, and then how bad their teak is. A little teak care goes a long way!

Sellers response:

"yes, it will pull you out of the water alot quicker,prop was changed and we still have stock prop, top speed 58 mph at 4600 rpm"

That seems fast to me, but he's the one that owns it I guess.

58 mph @ 4600 with the stock prop? He might need to adjust his Airguides.

I don't think that is with the stock prop but it seems as though the stock prop is still available to a buyer.

I wonder if he would trade straight up for a previously enjoyed 1998 Anniversary? I've been looking for a little bigger boat that can still slalom and foot withough giving up HP and speed to do it. :rolleyes:

What do stock airguides on a 205 go to? 50 right?

He has done the samething that was done to mine when my S/C was installed. Mount the doghouse on top a 2" base ring to raise it up.

His pictures show MC speedometers. I donít know if Airguide makes them or not, but this was the same speedo that came on my 95 Maristar. They read 0 to 60 MPH and are worthless for skiing. I pulled mine out and put in an actual Airguide.

Whatever his actual top speed is, if itís close to 58, Iíd love to take it for a Sunday drive!

All depends on what prop is on it as far as speed.

But it pulls like an 18 wheeler no matter what!

Something smells funny.

To underturn (speed vs. RPM) by 1200 would require an enormous prop change. A swap from a 13x13 to a 14x18 would probably do it. Even with 100 extra hp (optimistic) from the SC, that boat wouldnt be able to get out of its own way out of the hole with a prop that size.

It would take quite a bit more than 400hp to push that boat 58mph too. Even with a legit 400hp (which I doubt) , I bet it wouldnt break 55mph. More likely, 52ish. It takes way more than 10hp to gain 1mph at those speeds with a slow ski boat hull. Ive added over 100hp to mine and only picked up 6mph... and Im still not breaking 50mph at ~350hp.

I had a 1988 17 ft sunbird corsair with a 2.3l 110 hp I/O omc cobra outdrive. I hated it , no power. Long story short I put in a 290HP 351 W ford and changed the outdrive. Stock prop for that outdrive was 14X19 3 blade. It slipped too much and the engine revved WAAY to high, over 5500rpm and still wanted to rev more. WAs very unhappy with performance. Installed a 14X25 3 blade bass boat prop. Things got interesting. The boat was okay out of the hole but had a midrange surge, when the propeller hooked up and the boat really took off, to the tune of over 65mph. Not what I wanted. Final propeller was a 4 blade 14X22 stainless prop. The boat would do about 62mph all day every day. Funny thing was when I'd drag race my buddies ski centurion ski boat it would be dead even till I got on plane. I would run away from him. It was my poor mans ski boat. I even put a tower on it. It made absolutely NO wake at speed. Pull a slalom ski right up no problem. Orginal engine and stock prop was a total DOG out of the hole and would do about 40mph. But I almost tripled horsepower and torque to do that. And propping it was not easy. I got a picture somewhere. It looked BONE stock. But as I got older and rode in a real skiboat I sold it. Moral of the story is it takes Major amounts of power to upgrade speed and my boat was little. So if the boat is larger I'll bet it takes more.
